It is obvious that there is an optimum chain length of diblock copolymer for minimizing the mean domain size. 所以,加入等量的嵌段共聚物,存在一个最佳的链长使体系的相区尺寸最小。
The invention relates to a drug delivery system of nanometer liver targeting amphiphilic block copolymer and a preparation method thereof. 本发明涉及一种纳米肝靶向两亲性嵌段共聚物给药系统及制备方法。
